[texts]Thermal Sinusoidal Vibration and Transient Response of Magnetostrictive Functionally Graded Material Plates without Shear Effects
The study of laminated magnetostrictive functionally graded material (FGM) plate without shear deformation under thermal sinusoidal vibration and transient response is calculated by using the generalized differential quadrature (GDQ) method. In the thermoelastic stress-strain relations that containing a power-law function of a two-material FGM plate, the linear temperature rise and the magnetostrictive coupling terms with velocity feedback control...

[texts]Control and Identification of Turbulent Boundary Layer Separation - Seifert, Avi
Effective delay of turbulent boundary layer separation could be achieved via closed-loop control. Constructing such a system requires that sensor data be processed, real-time, and fed into the controller to determine the output. Current methods for detection of turbulent boundary layer separation are lacking the capability of localized, fast and reliable identification of the boundary layer state. A method is proposed for short-time FFT processing of time series, measured by hot-film sensors, wi...

[texts]Time-Extended Payoffs for Collectives of Autonomous Agents - Tumer, Kagan
A collective is a set of self-interested agents which try to maximize their own utilities, along with a a well-defined, time-extended world utility function which rates the performance of the entire system. In this paper, we use theory of collectives to design time-extended payoff utilities for agents that are both aligned with the world utility, and are ''learnable'', i.e., the agents can readily see how their behavior affects their utility...

[texts]On the Possibility of Ill-Conditioned Covariance Matrices in the First-Order Two-Step Estimator - Garrison, James L.
The first-order two-step nonlinear estimator, when applied to a problem of orbital navigation, is found to occasionally produce first step covariance matrices with very low eigenvalues at certain trajectory points. This anomaly is the result of the linear approximation to the first step covariance propagation. The study of this anomaly begins with expressing the propagation of the first and second step covariance matrices in terms of a single matrix...

[texts]A study of the effects of relative humidity on small particle adhesion to surfaces - Whitfield, W. J.
Ambient dust ranging in size from less than one micron up to 140 microns was used as test particles. Relative humidities of 33% to 100% were used to condition test surfaces after loading with the test particles. A 20 psi nitrogen blowoff was used as the removal mechanism to test for particle adhesion. Particles were counted before and after blowoff to determine retention characteristics. Particle adhesion increased drastically as relative humidity increased above 50%...

[texts]Description of a mathematical model and computer simulation of separation of the nose cap from the solid rocket booster - Schwaniger, A. J., Jr.
A system of equations which models the motion of the Solid Rocket Booster Nose Cap upon separation is described. The computer program which utilizes these equations to generate nose cap trajectories is described in detail. Application of the program to simulate a rocket sled test of the nose cap separation is discussed and the results of the applications are presented. With the information given a user should be able to exercise the computer program with a minimum of effort.

[texts]Applications of Space-Filling-Curves to Cartesian Methods for CFD - Aftosmis, Michael J.
The proposed paper presents a variety novel uses of Space-Filling-Curves (SFCs) for Cartesian mesh methods in 0. While these techniques will be demonstrated using non-body-fitted Cartesian meshes, most are applicable on general body-fitted meshes -both structured and unstructured. We demonstrate the use of single O(N log N) SFC-based reordering to produce single-pass (O(N)) algorithms for mesh partitioning, multigrid coarsening, and inter-mesh interpolation...

[texts]Internal Dynamics and Boundary Forcing Characteristics Associated with Interannual Variability of the Asian Summer Monsoon - Lau, K.- M.
In this paper, we present a description of the internal dynamics and boundary forcing characteristics of two major components of the Asian summer monsoon (ASM), i.e., the South Asian (SAM) and the Southeast-East Asian monsoon (SEAM). The description is based on a new monsoon-climate paradigm in which the variability of ASM is considered as the outcome of the interplay of a ''fast'' and an ''intermediate'' monsoon subsystem, under the influenced of the ''slow'' varying external forcings...

Radar was used in Frunze in 1964 and 1965 to study meteors. The study was made to evaluate the accuracy of wind parameters measured in the meteor region of the atmosphere for small samples and unknown altitudes, as well as to evaluate the effect of using different space and time averaging methods on the accuracy of results obtained.

This investigation was designed to determine how a primitive vertebrate, the bullfrog tadpole, is able to sense and process gravitational stimuli. Because of the phylogenetic similarities of the vestibular systems in all vertebrates, the understanding of the gravitational reflexes in this relatively simple vertebrate should elucidate a skeletal framework on a elementary level, upon which the more elaborate reflexes of higher vertebrates may be constructed...

[texts]Experimental Investigation of Oscillatory Flow Pressure and Pressure Drop Through Complex Geometries - Ibrahim, Mounir B.
A series of experiments have been performed to investigate the oscillatory flow pressure and pressure drop through complex geometries. These experiments were conducted at the CSU-SLRE facility which is a horizontally opposed, two-piston, single-acting engine with a split crankshaft driving mechanism. Flow through a rectangular duct, with no insert (obstruction), was studied first. Then four different inserts were examined: Abrupt, Manifold, Diverging Short and Diverging Long...

[texts]Development of the silane process for the production of low-cost polysilicon - Iya, S. K
It was recognized that the traditional hot rod type deposition process for decomposing silane is energy intensive, and a different approach for converting silane to silicon was chosen. A 1200 metric tons/year capacity commercial plant was constructed in Moses Lake, Washington. A fluidized bed processor was chosen as the most promising technology and several encouraging test runs were conducted. This technology continues to be very promising in producing low cost polysilicon...
